A literature review was performed on an article published in the journal "otology and neurotology" in 2011 entitled "ossiculoplasty in intact stapes and malleus patients: a comparison of porps versus torps with malleus relocation and silastic banding techniques,? By robert vincent, maroeska rovers, nina mistry, john oates, neil sperling, and wilko grolman. The article discussed a study involving partial ossicular replacement prosthesis (porp). Within the 310 ears operated on in the porp group, there were 90 failures; 75 of which underwent revision surgery during the follow-up period. Issues reported in the article: 1. ) prosthesis dislocation (50 cases) 2. ) short prosthesis (13 cases) 3. ) prosthesis extrusion (5 cases) 4. ) stapes fixation (3 cases) 5. ) malleus ankylosis (2 cases) 6. ) one patient was re-operated for a tm perforation, and the position of the previous porp was found to be correct. 7. ) in 2 cases, it was not possible to clearly identify the cause of failure at the time of revision, and the patients were therefore classified as having "negative findings" (malleus and stapes were normal, and the position of the previous prosthesis was correct with the presence of a clear round window reflex). Further ossicular chain erosion was identified at the time of the revision. 8. ) erosion of the stapes superstructure (10 cases) 9. ) malleus erosion (2 cases) 10. ) in 27 cases, the previous porps were removed and replaced with a new porp positioned from malleus to stapes head. Of the 27 cases that underwent revision ossiculoplasty with porp, postoperative data were available for 26 cases, with a mean follow-up of 48. 4 months. Neither postoperative snhl nor prosthesis extrusion was observed in this group. 11. ) in 15 cases, the previous porps were replaced with a torp positioned from malleus to stapes footplate, and the silastic banding technique was used. Of the 15 cases that underwent revision ossiculoplasty with torp, postoperative data were available for 12 cases with a mean follow-up of 24 months. Neither postoperative snhl nor prosthesis extrusion was observed in this group.
